Additional Description
Remapping port designations
For security reasons the network administrator may wish to assign new/different port numbers to the Telnet, web browser, and direct access ports of the controller or to disable
one or more ports. Typically Telnet uses port 23, web access is via port 80 (HTTP), and direct access (to a serial port) is via port 2001.
ATTENTION:
• Do not set two or more ports to the same port number. Setting two ports to the same number could cause networking conflicts and
will also result in an E13 (invalid parameter) error.
• Ne pas installer deux ports ou plus sur le même numéro de port. Paramétrer deux ports sur le même numéro pourrait créer des
conflits réseau et provoquer également une erreur E13 (paramètre erroné).
NOTE:
If you remap a port, you must set the port number to 1024 or higher, unless you reset the port to the default number or disable the port by setting it to 0 .

Pmd port#
]
This command sets the initial (lowest) port
number for the range numbers assigned to
the serial ports for direct port access (see
pages
16 and 17 for port locations and
see page 50 for more on direct access ).
Default port numbers for direct access start at
2001 and go up to 2007 (see the note at left
or the
diagram on page 51).
NOTE: The reserved TCP port numbers (2001-2003) for direct port access are assigned
by default as follows:
•
2001 = front panel Config port
•
2002 = Display RS-232/IR port
•
2003 = MLS port
